Ways of extracting CBD from industrial marijuana

Views: 7    

Industrial hemp, also known as hemp, is quite different from hemp. The THC content of cannabis is 5% - 20%, and the higher can reach 25% - 30%, while the content of hallucinogenic component THC of industrial cannabis is less than 0.3%, which is a variety type of non-toxic use value.

Cannabinoid has a wide variety and complex molecular structure. The extraction technology has become the technical barrier of the industrial marijuana industry, and it is also the core weight of the strength and competitiveness of enterprises.


How to extract cannabinoid?


Carbon dioxide extraction

Carbon dioxide extraction is divided into supercritical, subcritical and "medium key" categories, which does not involve the use of chemical solvents to protect CBD and other beneficial compounds.

Solvent extraction

Solvent extraction usually uses ethanol and butane as solvents to extract from hemp plant accessories. The combination of the two is good, simple and easy to operate, and can be operated at home. Under the condition of ensuring the extraction rate and purity, the method adopts solvent extraction in the whole process, avoids the use and residue of toxic organic solvents such as petroleum ether, and ensures the safety of the product.

Olive oil extraction

Heat the plant at a specific temperature for a period of time to activate plant chemicals, add olive oil and heat it for a period of time to finally obtain cannabinoid.

Dry ice extraction

Cut the hemp plant into blocks, put it into a bucket, cover it with ice, turn it upside down, and then filter the mixture several times with a mesh bag, and finally dry the extract until it becomes powder. This method requires time and energy, but it can also be operated at home.

In addition, there are many methods to obtain cannabinoids, such as cultivating transgenic cannabis, biosynthesis and chemical synthesis.


The objective of cannabinoid extraction technology is to improve the extraction rate and purity of cannabinoid, remove thc residue as much as possible, avoid the use of toxic organic solvents as much as possible, ensure product safety and environmental protection, and reduce the cost as much as possible. Among the current cannabinoid acquisition methods, skilled extraction method still occupies the mainstream. Biosynthesis and chemical synthesis are the main directions for cannabinoid acquisition in the future.
